Prestige Bias

Prestige bias is a selective pressure in cultural evolution whereby individuals preferentially copy the behaviors, beliefs, and practices of high-status or successful individuals, rather than evaluating the traits on their intrinsic merits. It is one of the core transmission biases identified by Boyd and Richerson (alongside conformist transmission and content bias), and it operates as a cognitive shortcut: status is treated as a proxy for competence, and copying the successful is often more efficient than individual trial-and-error learning. Prestige bias explains the rapid spread of innovations, the persistence of harmful practices associated with high-status individuals, and the formation of status hierarchies as information structures rather than merely dominance orders. The mechanism is not unique to humans: social learning in other primates and birds shows similar patterns of preferential copying of dominant or successful individuals.
